  • Send email once FFMPEG video conversion has completed (php)

    14 juin 2012, par Dino

    I have a basic php script which converts an avi using ffmpeg :

    <?php
    
if (exec("/usr/bin/ffmpeg -i testvideo.avi -sameq -ar 22050 convertvideo.mp4 2> logfile.log")){ 
    
echo "Success";
    
}else{ 
    
    echo "Error"; 
    
}
    
?>

    now as an extension to this I would like to use php to check if the file is still being converted if not an email should be sent can anyone advise how I can achieve this ?

    Also despite using the code above and the file being converted successfully, the output I always get is "Error", can anyone help with this as well ?

    Thanks

  • How to start an FFmpeg process, create a pipe and write data from the parent process ?

    3 mai 2021, par xlxs

    My code is based on https://stackoverflow.com/a/32279430/5941827.

    


    I run FFmpeg with the following params :

    


    std::stringstream sstm;
sstm << "ffmpeg -loglevel error -y -f rawvideo -vcodec rawvideo -s " << std::to_string(width) << "x" << std::to_string(height) //
        << " -pix_fmt rgb24 -framerate " << std::to_string(fps) << " -i - -c:v libx264 -preset " << getPreset(encodeSpeed) << //
        " -crf " << std::to_string(crf) << " -shortest " << path;


    


    (the variables are initialized in a class constructor correctly)

    


    Then I open the pipe with pPipe = popen(sstm.str().c_str(), "w").The problem is after I fwrite to it and calling fclose, based on the contents I write sometimes less or more bytes reach FFmpeg, and I get

    


    [rawvideo @ 000000000010c3df] Invalid buffer size, packet size 196606 < expected frame_size 196608
Error while decoding stream #0:0: Invalid argument


    


    The saved output video usually has one frame more or less than the expected.
I have checked the array I'm sending trough the pipe with fwrite and it's size is correct.
It appears that based on the data I send some bytes don't get there, or more bytes than I send go through the pipe.

    


    I have also tried two different FFmpeg versions, but with the same error message.

    


  • A very simple lightweight video editor

    11 novembre 2011, par algorithmicCoder

    I want to make an editor that does the following :

    1) takes an mp3 audio file

    2) Takes a picture —a jpg file

    3) Outputs a simple video format e.g. .mov which consists of the jpg file with the mp3 file in the background

    4) Does NOTHING else

    I want to use this as a project to learn just the basics of all this stuff however I do not want to code basic things by hand. Where do I start and what key steps do I take to accomplish this ?

    I am decent with PHP and Java and do not mind learning Python for this. I actually would ideally want to write this in Python to gain experience.

    Thanks !
